Briefly describe the behavior of unburned pulverized coal in the blast furnace
(1) Participate in carbon gasification reaction (2) Participate in carburizing reaction (3) Mix in slag, affect the fluidity of slag
What are the advantages of ferritic rolling technology?
(1) reduce heating energy consumption; (2) increase metal yield; (3) reduce ton steel roll consumption;
What is the role of the secondary combustion oxygen lance?
By supplying oxygen, the CO gas discharged from the molten pool is partially burned, and the heat in the furnace is supplemented to secondary combustion.

Briefly describe the erosion mechanism of Mg-C brick lining?
The carbon in the reaction layer has been oxidized, and Fe2O3 and SiO2 in the slag invade the brick to form a low melting point substance with MgO and CaO.
What is the bottom of the furnace? What is the main reason for the rise in the bottom of the furnace?
The so-called bottom rise is the gradual increase of the bottom of the furnace during the smelting process, as if it is on the original lining, and a new layer of refractory material is applied. This is a new problem caused by improper operation of dolomite slag.
